In computer science and data management, a commit is the making of a set of tentative changes permanent, marking the end of a transaction and providing Durability to ACID transactions. A commit is an act of committing. The record of commits is called the commit log.
In terms of transactions, the opposite of commit is to discard the tentative changes of a transaction, a rollback.
COMMIT statement in SQL ends a transaction within a relational database management system (RDBMS) and makes all changes visible to other users. The general format is to issue a
BEGIN WORK (or
BEGIN TRANSACTION, depending on the database vendor) statement, one or more SQL statements, and then the
COMMIT statement. Alternatively, a
ROLLBACK statement can be issued, which undoes all the work performed since
BEGIN WORK was issued. A
COMMIT statement will also release any existing savepoints that may be in use.
